Abstract
Description
- The invention relates to a transvaginal tube, more particularly to a transvaginal tube adapted for invasive laparoscopic surgery.
- Figure 1 shows a
transvaginal tube 1 for gynaecological laparoscopic surgical procedures described inUSP 6, 572, 631 B1 . Thetransvaginal tube 1 is mainly used to stretch the vagina of a patient for passage of a medical instrument through thetransvaginal tube 1 into the body of the patient to perform a laparoscopic surgery. Thetransvaginal tube 1 is generally hollow, and has atubular wall 101 that surrounds a tubular axis and that defines achannel 102. Thetubular wall 101 has aproximal end 104 for extension into the vagina up to the cervix, adistal end 103 opposite to theproximal end 104 and disposed externally of the body of the patient, and amiddle section 105 interposed between the proximal anddistal ends - Referring to Figure 2, as the
proximal end 104 of thetransvaginal tube 1 is not designed to have a relatively large opening, in use, when a medical instrument inserted through thechannel 102 to reach the uterus to perform a surgical operation, the operation is relatively difficult to conduct due to limited available room. - Furthermore, if the
transvaginal tube 1 is formed from relatively soft silicone rubber or TPR (thermoplastic rubber) for the sake of the patient's comfort, thetransvaginal tube 1 is likely to deform after being inserted into the vagina, which may even obstruct smooth performance of the surgical procedure. If thetubular wall 101 is formed to have a relatively large thickness in order to prevent undesirable deformation of thetransvaginal tube 1, this may, however, results in discomfort on the patient's part. - In addition, since the cross-section of the
tubular wall 101 is generally uniform and invariable, thetransvaginal tube 1 is unable to fit different patients and needs to be made into different sizes. - Therefore, the main object of the present invention is to provide a transvaginal tube for laparoscopic surgery, which has a flared insert end section to provide more room for facilitating surgical operation.
- According to this invention, a transvaginal tube for laparoscopic surgery includes a tubular wall defining a longitudinal axis and including an outer end section, an insert end section, and an intermediate section interconnecting the insert end section and the outer end section. The insert end section has a terminating end, and flares to the terminating end from a juncture of the intermediate section and the insert end section so that the terminating end has a cross-section larger than that of the juncture.
- Other features and advantages of the present invention will become apparent in the following detailed description of the preferred embodiment with reference to the accompanying drawings, of which:
- Figure 1 is a schematic sectional view of a conventional transvaginal tube;
- Figure 2 is a fragmentary schematic view of the conventional transvaginal tube in situ;
- Figure 3 is a sectional view of a preferred embodiment of a transvaginal tube according to this invention;
- Figure 4 is a top view of the preferred embodiment;
- Figure 5 is a schematic view of the preferred embodiment, showing how an insert end section is pressed and deformed; and
- Figure 6 is a fragmentary schematic view illustrating the preferred embodiment in situ.
- Referring to Figures 3 to 6, the preferred embodiment of a
transvaginal tube 100 for laparoscopic surgery according to the present invention is adapted to be inserted into thevagina 200 of a patient to be proximate to thecervical neck 210 and the uterus opening 230 so as to enable inspection and surgical operation of theuterus 220. Thetransvaginal tube 100 is preferably formed from a material with resilience, such as silicone rubber and TPR (thermoplastic rubber). As shown, thetransvaginal tube 100 includes atubularwall 10 defining alongitudinalaxis (L) and confining achannel 14 therein. In this embodiment, the longitudinal axis (L) is curved. Thetubular wall 10 includes anouter end section 11, aninsert end section 12 opposite to theouter end section 11, and anintermediate section 13 interconnecting theinsert end section 12 and theouter end section 11. Theinsert end section 12 has aterminating end 123 which lies in a plane that is non-normal to the longitudinal axis (L) and which has atop edge 123" and a bottom edge 123'. Theinsert end section 12 flares to the terminatingend 123 from ajuncture 121 of theintermediate section 13 and theinsert end section 12 so that the terminatingend 123 has a cross-section larger than that of thejuncture 121. Thetubular wall 10 has a wall thickness which is tapered toward the terminatingend 123 from thejuncture 121. That is, the wall thickness (T) of thetubular wall 10 at thejuncture 121 is greater than the wall thickness (t) at the terminatingend 123. Furthermore, theinsert end section 12 includes a plurality ofanti-slip depressions 124 formed in an outer surface thereof. - In use, referring to Figure 5, the
insert end section 12 is pressed flat (i.e., by pressing thetop edge 123" against the bottom edge 123'), with the lateral sides squeezed in, so that theinsert end section 12 becomes smaller in cross-section to facilitate insertion thereof into the patient'svagina 200 for laparoscopic surgery. Referring to Figure 6, when theinsert end section 12 reaches thecervical neck 210 of the patient, theinsert end section 12 will expand due to the resilience thereof. As the terminatingend 123 lies in a plane non-normal to the longitudinal axis (L), i.e., theterminating end 123 has an inclined or beveled profile, it can fit snugly around thecervical neck 210. Thus, medical personnel can perform laparoscopic surgery or the like using thetransvaginal tube 100 of this invention. - In view of the construction of the
transvaginal tube 100, this invention has the following advantageous effects: - 1. The configuration of the flared
insert end section 12 provides more room to facilitate surgical operation. - 2. The beveled configuration of the terminating
end 123 provides certain directionality when theinsert end section 12 is squeezed for insertion into thevagina 200. Besides, the beveled terminatingend 123 can fit snugly and relatively securely around thecervical neck 210. - 3. As the wall thickness (T) of the
tubular wall 10 at thejuncture 121 is greater than the wall thickness (t) at the terminatingend 123, theinsert end section 12 can be pressed and deformed with relative ease, and can render thetransvaginal tube 100 suitable for use in different patients. - 4. The arrangement of the
anti-slip depressions 124 helps prevent outward slippage of thetransvaginal tube 100 during insertion thereof into the patient'svagina 200 while causing no discomfort to the patient.
